Type for object in React/Typescript

Question

What is the type for a object in React/Typescript for example:

const [value, setValue] = React.useState<any>({});

if I need to define it as an object what type would I put in, instead of <any>

If you know that it is an object but you don't know the keys and values go with Record<PropertyKey, unknown>. If you know that keys are strings, use Record<string, unknown> — captain-yossarian from Ukraine

Well what are you planning to put it that object? The more information you give the compiler, the more helpful it can be. — jonrsharpe

interface MyObject {
  [k: string]: any;
}

const [value, setValue] = React.useState<MyObject>({});

[k: string]: any; means that property must be a string, and it's value are any.
